[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For reference Figure 1-2 The utility model is described as follows:

[0027] Embodiment 1: A thickness-adjustable glass clamping device comprises a circular clamping piece 1, which is used to directly contact and clamp the glass. Its larger contact surface can distribute pressure more evenly and reduce local damage to the glass. A screw 2 is fixedly connected to the center of the right end face of the clamping piece 1. The screw 2 is cylindrical and serves as a connecting and transmission component, providing a basis for the movement and adjustment of the adjustment sleeve 3.

[0028] The screw rod 2 is threadedly connected with an adjusting sleeve 3, which is cylindrical, and the center of the adjusting sleeve 3 is provided with a threaded hole 6 connected to the screw rod 2. By rotating the adjusting sleeve 3, it can be moved axially on the screw rod 2, thereby achieving thickness adjustment of the clamping device. The center of the left end face of the adjusting sleeve 3 is provided with a circular mounting groove 7, which is coaxial with and connected to the threaded hole 6. The mounting groove 7 is used to install the spring 5, providing a fixed position and space for the spring 5.

[0029] The adjusting sleeve 3 is movably connected with a clamping sleeve 4, which can rotate and slide, and can flexibly rotate and slide on the adjusting sleeve 3, and work in cooperation with the adjusting sleeve 3. The clamping sleeve 4 is cylindrical, and is located between the clamping sheet 1 and the adjusting sleeve 3. The clamping sleeve 4 is a shell structure that is opened toward the adjusting sleeve 3, which is convenient for assembly with the adjusting sleeve 3 and the clamping sleeve 4, and also provides a space for accommodating the internal spring 5. The center of the clamping sleeve 4 is provided with a through hole 8 for the screw 2 to pass through, so as to ensure that the clamping sleeve 4 can move along the axial direction of the screw 2 during the adjustment process. The left end of the adjusting sleeve 3 is adapted to be connected to the inner side of the clamping sleeve 4, and the inner diameter of the clamping sleeve 4 is equal to the outer diameter of the left end of the adjusting sleeve 3. A limiting ring 9 is provided on the outer side wall of the right end of the adjusting sleeve 3 to limit the clamping sleeve 4 from sliding out excessively from the right end of the adjusting sleeve 3, so as to ensure the integrity and stability of the device.

[0030] A spring 5 is provided between the clamping sleeve 4 and the adjusting sleeve 3. The spring 5 is installed in the mounting groove 7. The outer diameter of the spring 5 is equal to the diameter of the mounting groove 7. The spring 5 installed in the mounting groove 7 can play a buffering role when clamping the glass to prevent the glass from being damaged by the instantaneous excessive clamping force. When the clamping device is released, the elastic force of the spring 5 can help the clamping sleeve 4 to reset and form an elastic clamping on the glass.

[0031] The advantages of this thickness-adjustable glass clamping device include:

[0032] Precise adjustment can be achieved by rotating the adjustment sleeve 3 according to the different thicknesses of the glass to achieve precise clamping thickness adjustment.

[0033] Buffer protection and elastic clamping: the existence of the spring 5 effectively protects the glass, reduces the impact during the clamping process, and forms elastic clamping for the glass.

[0034] In summary, this thickness-adjustable glass clamping device achieves effective clamping and protection of glass of different thicknesses through ingenious structural design.

[0035] A connecting hole 10 is provided on the left end surface of the adjusting sleeve 3. There are two connecting holes 10. The two connecting holes 10 are symmetrically arranged about the center of the adjusting sleeve 3. The two connecting holes 10 are symmetrically arranged about the center of the adjusting sleeve 3, so that the force distribution of the adjusting rod 11 on the clamping sleeve 4 is more uniform, ensuring the stability and balance of the adjustment process. The connecting hole 10 is internally threaded with the adjusting rod 11. The threaded connection between the adjusting rod 11 and the connecting hole 10 can achieve precise length adjustment and maintain a stable position after the adjustment is completed. The adjusting rod 11 is against the clamping sleeve 4. By adjusting the length of the adjusting rod 11 extending on the clamping sleeve 4, the degree of compression of the spring 5 can be adjusted, and the elastic force generated by the spring 5 can be adjusted.

[0036] By rotating the adjusting rod 11 and changing the length of the adjusting rod 11 extending from the clamping sleeve 4, the compression degree of the spring 5 can be directly affected. When the extending length of the adjusting rod 11 increases, the compression degree of the spring 5 is reduced; conversely, when the extending length decreases, the spring 5 is further compressed. The spring 5 is compressed in the mounting groove 7. Since the degree of compression of the spring 5 determines the magnitude of the elastic force it generates, the elastic force of the spring 5 can be accurately controlled by adjusting the adjusting rod 11 to adjust the elastic clamping force on the glass.

[0037] A clamping pad 12 is provided between the clamping sleeve 4 and the clamping sheet 1. Functions of the clamping pad 12: Increase friction. The clamping pad 12 can increase the friction when in contact with the glass, making the glass less likely to slide after being clamped, thereby improving the stability of clamping. Protect the glass, prevent the clamping sleeve 4 and the clamping sheet 1 from directly contacting the glass, thereby reducing scratches and damage to the glass surface, especially for glass with high surface quality requirements, which plays a good protective role. Buffering effect. During the clamping process, the clamping pad 12 can absorb part of the impact force, play a buffering effect, and reduce the risk of glass breaking due to excessive instantaneous clamping force.

[0038] Material selection of the clamping pad 12: Soft material, usually rubber, silicone, soft plastic and other materials with certain elasticity and softness are selected to achieve the above-mentioned protection and buffering functions. Wear resistance, select materials with good wear resistance to ensure that they can still maintain good performance after repeated use.

[0039] A connecting pipe 13 is provided at the center of the right end surface of the clamping piece 1, and the connecting pipe 13 can extend into the clamping sleeve 4 through the through hole 8. The connection and cooperation between the clamping piece 1 and the clamping sleeve 4 are increased, which helps to improve the structural integrity and stability of the entire clamping device.

[0040] Here’s how it works:

[0041] According to the thickness of the glass to be clamped, the adjusting sleeve 3 is rotated. Since the adjusting sleeve 3 is threadedly connected to the screw rod 2, when the adjusting sleeve 3 is rotated, it will move along the axial direction of the screw rod 2, thereby changing the distance between the clamping piece 1 and the clamping sleeve 4. When the distance is adjusted appropriately, the glass is placed between the clamping piece 1 and the clamping sleeve 4. At this time, the clamping sleeve 4 is continued to be pushed closer to the clamping piece 1 to compress the spring 5. The elastic force generated by the compression of the spring 5 will act on the clamping sleeve 4, so that the clamping sleeve 4 and the clamping piece 1 clamp the glass together. The compression degree of the spring 5 can be further finely adjusted by the adjusting rod 11, thereby adjusting the elastic force generated by the spring 5.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
